Angular material 错误"/节点“U模块/cdk表格导出器/cdk-table-exporter.d.ts没有选择器，请添加它”；在构建角度应用程序时

我安装了以下依赖项，仅用于在angular 8中使用mat table exporter：

npm install mat-table-exporter --save 

现在，当我使用以下命令构建角度应用程序时：

ng build --prod --build-optimizer --aot --base-href=/application_base_name

我得到如下所示的错误：

PS C:\GitRepositories\cricket_aiops_dashboard\Client_Side>ng build --prod --build-optimizer --aot --base-href=/application_base_name
Your global Angular CLI version (9.1.0) is greater than your local
version (8.3.26). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

ERROR in Directive CdkTableExporter in C:/../Client_Side/node_modules/cdk-table-exporter/cdk-table-exporter.d.ts has no selector, please add it!

我试图通过安装dependency:npm install——保存cdk表导出器，然后构建我的应用程序来解决这个问题，但即使在那个时候它也不起作用

请帮忙

如果您使用的是低于9的角度版本，则应使用mat table-exporter@1.2.5. 使用此->npm安装--保存mat表-exporter@1.2.5

如果已安装mat table exporter，请卸载它。 首先卸载mat表导出器，然后卸载cdk表导出器。 然后安装垫台-exporter@1.2.5使用上述命令

我从这个链接得到了答案：我从这个链接得到了答案：顺便说一句，你甚至不需要卸载，我只是运行了npm安装--保存mat表-exporter@1.2.5如果不卸载以前的版本并修复它：）顺便说一句，你甚至不需要卸载，我刚刚运行了npm安装--保存mat表-exporter@1.2.5没有卸载以前的版本，并且已修复：）
